Instead of parsing ISA extensions separately for each hart in the
generic_extensions_init() function, it is better to parse ISA extensions
for all available harts in the cold boot path. Also, this allows us
to remove fdt_isa_bitmap from scratch space and directly initialize
"extensions" in struct sbi_hart_features for each hart.

Now that all of the overrides are modifying generic_platform_ops
directly, remove the unused hooks and forwarding functions. The
remaining members of struct platform_override match struct fdt_driver,
so use that type instead. This allows a future commit to reuse the
fdt_driver-based init function.

Switch all existing platform overrides to use the helper pattern instead
of the platform hooks. After this commit, only the .match_table and
.init members of struct platform_override are used.
There are two minor behavioral differences:
- For Allwinner D1, fdt_add_cpu_idle_states() is now called before the
body of generic_final_init(). This should have no functional impact.
- For StarFive JH7110, if the /chosen/starfive,boot-hart-id property is
missing, the code now falls back to using generic_coldboot_harts,
instead of accepting any hart.

Several of these override functions access the FDT blob. Explicitly
indicate which callbacks are allowed to modify the FDT blob by passing
the parameter as a possibly-const pointer. This also reduces code size
by deduplicating the call to fdt_get_address().
